Runner

Overview In today’s high-performance and concurrent computing environments, effectively processing a stream of messages using a mix of purely computational functions and remote procedure calls has become a significant challenge. The Go programming language is designed to handle concurrency well, but when it comes to managing a hybrid load, even Go can struggle to achieve optimal CPU utilization. In this article, we will discuss the Hybrid Handler pattern, an efficient and unified approach to address this challenge. ...

Again and again, a concurrent pattern emerges from the need to control goroutine lifecycles and handle their errors, and I call it the “Runner Pattern”. The runner interface and its contract The pattern is as simple as a single-method interface: // Runner defines the Run method to be executed within a goroutine type Runner interface { Run(ctx context.Context) error } The contract of the interface covers two aspects. On the goroutine lifecycle, the Run method will block until one of the following occurs: ...
